17mm drive flange

[Driftwood]

I had a bit of an "off" whilst messing about in a car park and stuffed my car sideways into a kerb. It was to be expected, really, off road tyres and tarmac don't mix. The car is ok but the drive nuts/flanges and wheel nuts are wrecked. Are the flanges/nuts a universal fitment or will I have to buy them from the makers? The car is a GV Rex X. My tyres are now almost bald. Any suggestions for a half decent set of on-road tyres?
